The rumour mill is turning again, and this time it’s to suggest that Apple will reveal a new line of iMacs, MacBook Pros with Retina displays, and Mac Minis at next weeks iPad Mini Media Event.Severalprominentsites are suggesting that the new iMac and Mac Mini models could well be complete redesigns, with some suggesting the iMac could take on a tear-drop form factor, with new internals. Other reports claim that the maximum amount of RAM in built-to-order iMacs and Mac Minis will be doubled, offering up to 32 GB for those who want to push it beyond the included hardware.

Will we see new 13" Retina MacBook Pros next week?

News of a 13-inch MacBook Pro with Retina display have also been picking up speed recently, with some suggesting that it will add a sixth laptop to Apple’s current line-up. While the current MacBook Pro with Retina display is one of only two 15-inch machines available from Apple, a 13-inch model would have to compete with the 13-inch MacBook Pro, as well as the equally-proportioned MacBook Air.

Despite these rumours of new designs, 9to5Mac have reported that the new iMac and Mac Mini models will retain the current pricing across the world. If this claim is true, it seems unlikely that Apple would be able to add a Retina Display to the new iMacs; the expensive technology would significantly cut down the profits that Apple would make on each device.
